EDMUND S. MORGAN, OF JACKSONS MILLS, NEW JERSEY.

TYPE-WRITING MACHINE.

No. 912,7 10. Sp ecification of Application filed October 8,

To all whom it may concern:

Be it'known that I, EDMUND S. lVlORGAN, a citizen of the United States, residing at J acksons Mills, in the county of Ocean and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is s ecification, reference being had therein to t 1e accompanying drawings, which form a part thereof.

My invention relates to type writing machines, and more particularly to the connecting link between the type bars and the key levers.

' In type writing machines, it is not only es sential that the connecting link between the key lever and the type her be free from charaeteristics-permitting substantial elongation under the stress of use, but. it is reasonably necessary that the said link capable of longitudinal adjustment to take up lost. mo-

tion due to wear, or to facilitate adjusting the key levers and type bars, and be provided with means whereby the link may be conveniently attached to and removed from the type bar to facilitate assembling and repairs. Considerable difiiculty has been encountered heretofore in producing a link possessin these characteristics which has the desiret stre th. to withstand the stress 11 on the,

- con 1mg between the type.- bfar and t e link,

the ack ofspaoe in the basket necessitating a compactness of structure which. has resultedv in. a weakness in the. coupling st-ructure, or the abandonment of a couplmgat this pomt with re'sidtant difficulty in t e assembling and repair of the printing mechanism of the machine.

i The main; obj ect of the invention is to pro..- vide. a one'piece couplin for the connecting links or wires, whlch wi be so constructed and arranged as to'fit compactly in the type basket, and whichmay be readily connected to, and disconnected from the heel of the type bar.

Afurther object is to provide a connecting li k the coupling of which may be rigidly attached to the shank by a union which will not only impart strength and rigidity to the link at. the point of union, but one which will permit the rapid, accurate and inexpensive memblin of the links. p

i A. still 1 'rther object is to rovide a lipk which may be made, of wirert rcugsout, in cluding the jaws of the coupling, thus affording a. structure-which may be madeon inex- Letters Patent. 7

which may be repeatedly coupled to or dis connected from the type bar without weakening the union between the coupling' and the shank. p I

A still further object is to provide a conof use, reasonable wear excepted.

- The, inventlon consists in a connectmg member formed of a continuous strand of .positeends formed into cooperating jaws. adapted to engage a type er, a shankadapted to. pass through said. coil and engage the. end thereof adjacent to said jaws, and means whereby said shank may be attached to a, key lever; and in such othernovel parts as are hereinafter set forth and described and more particularly pointed out in the claims hereto appended.

Referring to the drawings,-Fi ure 1 is a front elevation of a connecting lin embody ing the preferred form of my invention, a type bar and its bearings, and a portion of a standard ty e of key lever being shown in connection t erewith. Fig. 2 is a front elevation of the upper portion thereof; Figs. 3, 4, 5, 6, 7 and S are modified forms of the invention showing difi'erent manners of forming the coupling jaws; and Fig. 9 is a side view of the modification shown in Fig. 8.

Like letters refer to like parts throughout the several views.

In the 'embodiment of my invention shown as the referred form in the accomrpanying drawings, I have illustrated it as eing appliedto the well-known Remington I type of machine, the same being a down-pull A still further object is to provide a linkand arranged as to withstand all the stresses.

of illustration, my invention being appli-- cable to any macline of the same type.

Mv invention, however, relates to the connect To enable me to make the coupling member of one piece, and thus avoid the'necessity for soldered joints or' complicated locking jaws, I make tlte link of two members, a coupling member 9 and a shank h,providing suitable means for rigidly connecting these members andconnectingthe latter to the key lever e by means of the bracket This construction broadly is common to all forms of the inven- 't1on shown, the various modifications relating more particularly to the manner of forming the coupling jaws.

In the referred form of the invention, the coupling d is made of a continuous strand of round spring wire formed'intermediate its ends into a coil i, and the opposite ends thereof brought to one end of the coil and formed into the coupling jaws. The coil i, in tl: e preferred form of the'invention, of a size to permit one end ofv the 'wire j to be passed upwardly through the coil with tlte extreme end th ereof pro ecting above the coil to an extent to bring the coil well below the housing a. This end is formed into an eyelet y", tlte eye of which is of a size sligL tly in excess of tie gage of the wire used. The other end 7c of the wire forming the coupling is extended. upwardly from H e top ofsaid coupling in a plane substantially parallel to tlie end and a hook or tongue is formed thereof by bending in a pivotally connected to the type bar.

manner to obviate as much as ossible a tendency of said look to give un er the stresses of use. a tongue conveniently accessible to facilitate the disconnection of tie coupling jaws from the eyelet d. In forming this jaw of the cou ling, I bend the end 7c in a ring it direct y opposite the eyelet 7'', extending the wire in an upwardly loop to form the tongue 7c and bring the. wire, after forming said tongue, downwardly and through the ring k and projecting beyond same to a'n-extent which will permit it to "pass through and engage the eyelet j. This end, which I have designated at W, constitutes the other 0011 ling jaw by means of which the link mayF e or the convenience of this description, I shall designate the jaw the pivot-jaw and the I also so bend the end 76 as to form eyelet j as the keeper-jaw. It will be observed that the manneii of bending the end that the ring kwill serve as a reinforcement to the jaw, and thus minimize any tendency of the said jaw to straighten out and cause its disengagement from the type bar, or an downward strains from springing the free 'end of the said ja'w k The shank h is provided with a head h, ada ted to engage the top strand of the coili will have-no tendency to elongate said coil through the separation of the strands thereof. To avoidany possibility of elongation, however, I form a screw thread OIMSaId. shank and mount a jam-nut thereon, by means of which the coil is held firmlybetween the head it and the nut Z. This arrangement insures absolute rigidity of structure and prevents any elongation except through that of the metal itself. The lower end of the shank h is adjustably connected to the bracket f in the usual and well-known manner, a lock nut m being used to secure permanency of'the adjustment.

In the modification shown in structure is substantially the same as in the preferred form of the invention, the sole difinside of the coil, is brought up on the outside and the other end is formed into a tongue n by being turned upon itself, and is'turned at directly right angles without the formation of the ring, as in the'preferred form.

In the modification shown in Fig. 4, the construction is substantially the same as thatshown in Fig. 3, exce t that the kee er-j aw 0 is formed by a doubih eyelet and th I jaw 0 is formed by iorming a double eyelet and passing the end of the wire therethrough. In addition to these modifications, I provide. a sleeve 0 encircling the stem of the jaws so as to limit the extent of lateral movement of the said jaws. This form of the invention is adapted for use in machines wherein the space is insuflicient to permit the use of short stems formed by the ends of the wire, which necessitates the coil being closed to the jaws. In the modification shown in Fig. 5, the

shown in Fig. 3, the keeper-jaw '1) being formed. as in Fig. 4, and the pivot-jaw p being formed similarly to the said jaw shown in Fig. 3.

In the modification shown in Fig. 6, the construction of the keeper-j aw g is similar to that shown in Figs. 4 and 5, and the pivotj aw g is formed by making two loops in the wardly about the stem, upwardly and through said loops. In this form of the inlvention, which is designed for use similar. to

elongation of the connecting link. The keeper-jaw y" will, also,'serve to prevent the Fig. 3, the

By merely. releasing i lnstrument inserted between them, or by forcing the pivot-jaw forwardly by means of "as'sembled'by passing the latter through the coils andrigidly connect the shank to the bending, or by means of the screw thread formed, will cause them to snap to place, the

' each of these forms having characteristics that of Fig; 4, I twist the stems g for the purpose of limiting the elasticity -of s-ard stems. In the -modification shown in Fig. 7, the

the preferred form, and the pivot-jaw i" is formed bymerely bending the end of the wire or' reinforceme'nts of any character.

In the modification shown in Figs. Sand 9, the construction is the same as in Fig. 7, except' that the keeper-j aw s is formed by fiattherein adapted to receive the pivotal jaw s. It will be observed that in all-form's of the invention shown, the stems of the jaws are so offset relative to the axis of the coil as to properly center the strains relative to; the shank h and thus relieve both jaws from any lateral strains which would tend todisconnect the coupling from the heel of the-type bar. It will also be observed, by reference to the various modifications shown, that various methods of forming and reinforcing ing of the drawings being merely for the urpose of illustrating some of the ways 0 accomplishing the desired result. 4

In use, the coupling 9 and shank h are coil "5 of the former, and screwing the j am-nut Z to place, so as to firmly compress the said cou ling head. The link being thus assembler is attached to the key lever in the usual, and well known manner, and is adjusted bythereon of the bracket f to the desired length and osition. When it is desired to connect the ink to the type bar, it is merely. neces; sary to raise the said bar so as -to project the heel downwardly and s read the ends of the wire, or stems j, 7c,"unti .the endof the ivot jaw is beyond the said heel and aline with said stems the spring inherent to the material, of which said jaws and said stem are end of the pivot-jaw k passing through said opening and seating itself 7". When so positioned, the jaws are so compact as to readily pass within the brackets of the journal housing a and as the type bar islowered by the release of the key lever 6 said jaws will pass between said brackets with the tongue k projecting slightly above the bearings. -If it is desired to disconnect the link, such may be accomplished by spreading the stems by means of any desired the said tongue k The operation of all of the modifications shown in Figs. 3 to 9, inclusive, is substantially the same as that heretofore described,

essential to the inventionyto wit,a coil adapted to be engaged by the shank of the link, the opposite ends of which are projected upwardly forming substantially par- .allel stems of spring metal having, respectively, cofiiperating coupling jaws integral there-with and adapted to be closed and to be] held closed through the spring inherent to the wire, of which the stems are formed;

It is not my intention to limit the invention to the precise manner of bending the free ends of the coil to bring the coupling stems into the desired position, nor to form' the pivotjav s and the keeper-jaws, such be' largely a matter of mechanical detail foi lie purpose of adapting the inventionto' difierent ty es of machines and type bars.
